If you exceed the MOD, in the bottom row
the blinking MOD value is displayed with
MAX symbol so you can see by how much
you have exceeded it. In addition, MANTIS
will beep continuously. Both the blinking of
the MOD value and the beeping will continue
for as long as you stay deeper than the MOD.
4.8.9.7 CNS O
2
= 100%
WARNING
When the CNS O
2
reaches 100% there is
danger of oxygen toxicity. Start procedure to
terminate the dive.
MANTIS tracks your oxygen uptake via the
CNS
O
2
clock. If the calculated value of
CNS
O
2
reaches 100%, MANTIS will emit a
sequence of audible beeps for 12 seconds
and the symbol
O
2
% MAX will be blinking in the
bottom right corner. The blinking will continue
until the value of CNS
O
2
drops under 100%.
The audible signal stays on for as long as
the CNS O
2
value equals or exceeds 100%;
or until youl reach a depth where the ppO
2
is less than 0.5bar.
4.8.9.8 Missed decompression stop
WARNING
Violating a mandatory decompression obligation
may result in serious injury or fatal issue.
If in the presence of a required decompression
stop you ascend more than 0.5m/2ft above
the required stop, MANTIS will trigger an
alarm: the value of the current depth and the
value of the required stop depth will blink, and
a sequence of beeps will be heard. This will
continue for as long as you stay 0.5m/2ft or
more above the required stop.
4.8.9.9 High workload
If MANTIS detects a sufficient increase
in workload, no-stop times may shorten
and decompression stops can increase.
MANTIS warns you of this situation with an
audible beeps and shows the heart symbol.
